Elementary Particles of Conventional Field Theory as Regge Poles. IV [PDF]

, 1964
The usual field theory of spin 0 "nucleons" coupled to vector mesons (or heavy photons) is studied in order to find out whether the nucleon lies on a Regge trajectory.

Testing low-energy theorems in nucleon-nucleon scattering [PDF]

, 1999
Low energy theorems have been derived for the coefficients of the effective range expansion in {ital s}-wave nucleon-nucleon scattering valid to leading nontrivial order in an expansion-based {ital Q} counting, a scheme in which both m{sub {pi}} and 1/a (

Total hadronic cross sections at high energies in holographic QCD

Physics Letters B, 2019
We present our analysis on high energy hadron–hadron scattering in the framework of the holographic QCD. Combining the Brower–Polchinski–Strassler–Tan Pomeron exchange kernel and gravitational form factors of the involved hadrons which are obtained by ...

Three-nucleon force effects in the FSI configuration of the d(n, nn)p breakup reaction

SciPost Physics Proceedings, 2020
We investigated three-nucleon (3N) force effects in the final state interaction (FSI) configuration of the d(n, nn)p breakup reaction at the incoming nucleon energy E n = 200 MeV.

Mu and Tau Neutrino Thermalization and Production in Supernovae: Processes and Timescales

, 2000
We investigate the rates of production and thermalization of $\nu_\mu$ and $\nu_\tau$ neutrinos at temperatures and densities relevant to core-collapse supernovae and protoneutron stars.

Reduction of neutrino - nucleon scattering rate by nucleon - nucleon collisions [PDF]

, 1999
We studied possible modifications of the neutrino - nucleon scattering rate due to the nucleon - nucleon collisions in the hot dense matter which we find in the supernova core. We show that the finite width of the nucleon spectral function induced by the

Roy–Steiner-equation analysis of pion–nucleon scattering

EPJ Web of Conferences, 2017
Low-energy pion–nucleon scattering is relevant for many areas in nuclear and hadronic physics, ranging from the scalar couplings of the nucleon to the long-range part of two-pion-exchange potentials and three-nucleon forces in Chiral Effective Field ...

Matter Density Distributions, Root-mean Square Radii and Elastic Electron Scattering Form Factors of Some Exotic Nuclei (17B, 11Li, 8He)

Iraqi Journal of Physics, 2021
The two-neutron halo-nuclei (17B, 11Li, 8He) was investigated using a two-body nucleon density distribution (2BNDD) with two frequency shell model (TFSM).

Multiple-Scattering Series For Color Transparency

, 1992
Color transparency CT depends on the formation of a wavepacket of small spatial extent. It is useful to interpret experimental searches for CT with a multiple scattering scattering series based on wavepacket-nucleon scattering instead of the standard one

Antinucleon-nucleon interaction in chiral effective field theory

EPJ Web of Conferences, 2018
A study of the antinucleon-nucleon interaction within chiral effective theory is presented. This novel approach suggested by Weinberg for investigating nucleon-nucleon interaction can be adapted straightforwardly to the antinucleon-system.
